I received my M.S. from Yonsei University, where I worked at CVLab, advised by Prof. Bumsub Ham, and am also affiliated with KDST in Kyung Hee University (formerly at KIST), co-advised by Prof. Suhyun Kim.

I am broadly interested in building trustworthy and safe AI that can operate reliably under real-world conditions.

If you have any questions, feel free to contact me!
